Repo is git fetched to the latest (today's). Did I miss something?
Thanks,
Przemek.
compiling with gcc 8.2.0-r2. Created attachment 141248 [details] pstore kernel oops message with applied patches (In reply to Przemek from comment #7) > Repo is git fetched to the latest (today's). Did I miss something? > > Thanks, > Przemek. Yes I did. Fetching once again the online repo resolved the problem with compilation, but those patches didnt help with kernel oops. I have attached full pstore message log. Thanks, Przemek. Thanks for testing the patches. Looks like there's still an issue with DC. I appear to be experiencing the same bug. Same set of internal and external connectors. My hardware is Lenovo G75 A10-7300 [Kaveri] Kernel booted with - amdgpu.cik_support=1 - radeon.cik_support=0 - amdgpu.dc=1 - drm.debug=1 The internal (eDP) display fails to work. The VGA display doesn't work either (as expected), and I can't comment on the HDMI as I don't have an HDMI monitor. Used ssh to get in and copy the dmesg buffer. I do not have the capability to compile kernel+patches. Sorry. graaskaeg [ 1.963843] [drm] radeon kernel modesetting enabled.

_No_ more kernel _oops_, both screens lights up properly (eDP and HDMI, for VGA there is still " [drm] Unsupported Connector type:5!"). I have no idea what have changed, but thank you very much! BTW. there is an error in dmesg: "[drm:dm_pp_get_static_clocks [amdgpu]] *ERROR* DM_PPLIB: invalid powerlevel state: 0!" but I think this is another story. I am closing this bug report, as RESOLVED - FIXED. Pontus Gråskæg, if kernel compiled from the latest git repo sync (git://people.freedesktop.org/~agd5f/linux) does not work for you feel free to reopen it. Thanks, Przemek.
